6 sdt - DTrace statically defined tracing provider
7
9 The sdt driver is a DTrace dynamic tracing provider that performs
10 dynamic instrumentation at statically-defined locations in the Solaris
11 kernel.
12
13
14 The sdt provider allows kernel developers to explicitly create probes
15 at formally designated locations in the operating system kernel and
16 loadable modules, allowing the implementor to consciously choose the
17 points in their code that are desired probe points, and to convey some
18 semantic knowledge about that point with the choice of probe name and a
19 relevant set of arguments.
20
21
22 The sdt driver is not a public interface and you access instrumentation
23 offered by this provider through DTrace. Refer to the Solaris Dynamic
24 Tracing Guide for a description of the public documented interfaces
25 available for the DTrace facility and the probes offered by the sdt
26 provider.
